Knockerball Frequently Asked Questions

We provide the full setup of the Knockerballs (delivery, inflation and breakdown). We will also provide you with some options of "games" to play and soccer nets & soccer ball with a minimum rental of 6 balls.

An all-encompassing, protective, safe, single chambered ball of air with inner handles and shoulder straps that enables you to almost literally defy gravity and defy pain. You only need one to get started, practice your rolls and flips.

When choosing a pump to fill your Knockerball you want to look for one designed for large inflatables. You can even use a shop vac on reverse with a half inch cone attachment. Fill time is generally less than a minute depending on the size pump you are utilizing. Your pump should have a fill capacity of 2.8 psi. Note, you want to make sure not to over-inflate your Knockerball. We recommend about a 2" depression with your hand when you pushed on a filled ball. It should be firm but not hard. If it is over-inflated, when the players hit each other it can cause a breach. You need to allow a little space for the air to move inside the ball upon impact.

All participants under 18 must have adult supervision. KNOCKERBALL'S are available in two sizes currently: 1.2 meter or medium recommended for male or female under 5 feet: 1.5 meter or large for those over 5 feet. Here is why. It is important that your KNOCKERBALL is adjusted to cover from above your head to just above your knees. This will ensure that you maintain proper protection for rougher play. Remember to adjust the shoulder straps accordingly so to obtain optimum bodily coverage. Please refer to directions for restrictions. Remember NO jumping head to head or spearing.

We do not recommend subjecting Knockerball's to extreme cold weather. Whether you are using a PVC or TPU unit it is highly recommended to only use this product in temperatures ranging from 40 degrees to 85 degrees. Extreme cold may make the material brittle therefore rendering your Knockerball unusable.

Additionally, do not subject the product to extended exposure to UV light ( over 72 hours) as this exposure may have a similar effect on the raw materials and joints. Obviously, you will be playing Knockerball in the sun but we suggest not to store them or leave them inflated for days at a time in the hot sun.

To really be able to use the Knockerball we recommend at least 4' 0" for the 1.2 ball because the balls do weigh 14-17lbs. But to just get inside of a ball and roll around we have had many young children have a blast. Anyone over 5' foot will have more fun with the 1.5 ball.
